I am tyring to run my jest tests but keep getting the error below, how can I get my jest tests to run?

● Test suite failed to run
Requires Babel "^7.0.0-0", but was loaded with "6.26.3". If you are sure you have a compatible version of @babel/core, it is likely that something in your build process is loading the wrong version. Inspect the stack trace of this error to look for the first entry that doesn't mention "@babel/core" or "babel-core" to see what is calling Babel.
at throwVersionError (node_modules/@babel/helper-plugin-utils/lib/index.js:65:11)

I have followed the instruction here, but still no joy.

I had the same issue. Upgrading to jest@24.0.0 worked for me.
